Alessandro Lazarotti created AS7-5102: ----------------------------------------- Summary: CLONE - PersistenceUnitSearch violates the JPA spec Key: AS7-5102 URL: https://issues.jboss.org/browse/AS7-5102 Project: Application Server 7 Issue Type: Bug Components: JPA / Hibernate Affects Versions: 7.1.1.Final Environment: Linux (Ubuntu, kernel v.3.0.0-12-generic), Java HotSpot SE Runtime Environment (build 1.6.0_31-b04) Reporter: Alessandro Lazarotti Assignee: Scott Marlow Fix For: 7.2.0.Alpha1 There is no ability to deploy EAR, which contains several EJB-JAR modules, when more then one of them defining a persistence unit and at least one of EJBs within module "expresses a dependency on a container-managed EntityManager and its associated persistence context" (e.g. using @PersistenceContext annotation) without specifying the unitName.

JPA 2.0 specification (in paragraph "8.2.2 Persistence Unit Scope") states that: "When referencing a persistence unit using the unitName annotation element or persistence- unit-name deployment descriptor element, the visibility scope of the persistence unit is determined by its point of definition: • A persistence unit that is defined at the level of an EJB-JAR, WAR, or application client jar is scoped to that EJB-JAR, WAR, or application jar respectively and is visible to the components defined in that jar or war." Although it says "when referencing... using the unitName", when in this case "unitName" attribute is omitted, I believe this (taking into account persistence units defined in other modules) is still a bug, cause: 1. The scope of a persistence unit is all the same implied by the spec, e.g. by sentences like this: "The persistence.xml file may be used to designate more than one persistence unit within the same scope. The persistence.xml file may be used to designate more than one persistence unit within the same scope." 2. AFAIK, neither JPA 2.0 nor EJB 3.1 specification defines any persistence unit choosing algorithm in case of unitName omission despite this attribute is optional. Code responsible for generating an aforementioned exception resides in org.jboss.as.jpa.container.PersistenceUnitSearch: PersistenceUnitsInApplication persistenceUnitsInApplication = DeploymentUtils.getTopDeploymentUnit(deploymentUnit).getAttachment(PersistenceUnitsInApplication.PERSISTENCE_UNITS_IN_APPLICATION); if (persistenceUnitsInApplication.getCount() > 1) { // AS7-2275 no unitName and there is more than one persistence unit; throw MESSAGES.noPUnitNameSpecifiedAndMultiplePersistenceUnits(persistenceUnitsInApplication.getCount(),DeploymentUtils.getTopDeploymentUnit(deploymentUnit)); } So, since a developer haven't defined any EAR-level persistence unit ant tries to inject EntityManager without using the unitName - all persistence unit defined in other EJB/WAR modules are taken into account and application is prevented from deploying because of "false ambiguity". -- This message is automatically generated by JIRA.
